This paper proposes a two pass and a three-pass authentication exchange schemes which combine public-key based on the mutual entity authentication with a Diffie-Hellman key derivation exchange. The security of key exchange of the proposed schemes depends on the discrete logarithm problem. The security of the entity authentication depends on that of the signature mechanism to be used in the proposed scheme. In comparison with the Kerberos, X.509 exchanges, and ISO 3-way authentication protocol, the proposed schemes ar not only simple and efficient, but also resistant to the full range of replay and interception attacks.
